Can you can butter? I had seen on the net sites that talked about canning butter. I am fairly new to canning. So far I have only made Jam and Salsa. I want to do a bunch of canning this summer. I was hoping to do vegies, soups and butter. I don't want to can something that will make my family sick though. We do use a water canner. Can you can potato soup? Sorry for so many quesitons I just have no clue about it. Thanks!
